Manuscript Summary: Manuscript compilation consisting mainly of grammatical texts, written in a variety of hands in about 800 in the monastery of St. Gall. Some of the texts in this codex are the oldest extant versions, and the text of the anonymous treatise De scansione heroyci versus et specie eorum is the only known surviving version in the world. Grammars include the Ars major and Ars minor by Donatus, a complilation of the two Donatus grammars by Peter of Pisa, the work De metris des Mallius Theodorus, the Ars grammatica by Diomedes, and both De arte metrica and De schematibus et tropis by the Venerable Bede.
